Sustained implementation of effective behavior support systems and practices is critical for improving academic and behavior outcomes for students with and without disabilities. Although implementation studies have identified variables facilitating sustained implementation of Tier 1 behavior support systems in schools, little research exists…

Children with complex communication needs (CCN) who use augmentative and alternative communication (AAC) often need more time to process and respond when communicating with others. This study employed a survival analysis approach exploring child response-time patterns following different communication opportunities for young children with CCN who…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

This study examined the diversity in feelings of loneliness among high-ability students. Individual differences (intelligence level, giftedness label, and personality) and differences in the social context (peer acceptance, peer rejection, victimization, and friendship quantity) of adolescents were considered as predictors of loneliness.…

This study investigated the typologies of teacher attitudes toward gifted students and gifted education, along with the predictors of such attitudes. For this purpose, surveys were administered to 339 teachers employed in a large faith-based school system in Australia. Analyses including factor analysis and latent profile analysis were performed…

Despite their negative effect, preschool suspension and expulsion are prevalent. Researchers have explored adverse childhood experiences and teachers' racial bias that link to disproportionate suspension and expulsion in preschools, but little research has investigated disability status as a risk factor. This study investigates the extent to which…

Special education teachers of color are underrepresented in research about attrition and retention, despite evidence of their role in the academic, social, and emotional success of students of color. We used critical quantitative methods and structural equation modeling to investigate the attrition and retention variability between special…

There is growing evidence that school starting age impacts children's likelihood of receiving special education services, but less is known about variations in this effect. Using a regression discontinuity design, I found that the youngest students in a kindergarten cohort are 40% more likely (p < 0.001) to be placed in special education than…

We used survey and administrative data from Washington State to assess the degree to which special education teacher preparation, district literacy instructional practices, and the alignment between preparation and practice were associated with the reading test score gains of students with high-incidence disabilities taught by early-career special…

A wide research base has documented the disproportional enrollment in K-12 special education and gifted and talented services across racial and socioeconomic lines. This study extends that knowledge base by integrating multiple population-level datasets to better understand predictors of access to and enrollment in gifted and talented services and…

Drawing from a social network perspective, we examined the extent to which children with and without disabilities play with each other in preschool inclusive classrooms and identified malleable child characteristics that would support children forming these cross-status play interactions. A total of 200 children with disabilities and 301 children…

We used data on the student teaching placements, degrees, teaching credentials, and workforce outcomes of more than 1,300 graduates of special education teacher education programs in Washington to provide a descriptive portrait of specific measures of special education teacher preparation and their relationships with workforce entry and…

Retaining teachers is an important priority for school leaders, especially in special education, a field with chronic shortages. We analyzed a nationally representative survey using conservation of resources theory to examine how job demands and resources interacted with one another and with teachers' assignments (i.e., as special and general…

Empirical studies investigating supplemental reading interventions for students with or at risk for reading disabilities in the early elementary grades have demonstrated a range of effect sizes. Identifying the findings from high-quality research can provide greater certainty of findings related to the effectiveness of supplemental reading…

Although reading outcomes for children with hearing loss are improving, too many of these children continue to display persistent reading difficulties. Because of these difficulties, there is an ongoing need to understand the nature of the relationships among decoding abilities, language skills, and reading achievement in this population more…
